Marley / MC Fluid Cooler/ Engineering Data: Freeze Prevention Fluid Cooler Coil Fluid Cooling Recirculating Water When the ambient temperature falls below 0°C, heat loss from the coil can be substantial even without recirculating water flowing over the coil. The process fluid, without an applied heat load, may be prone to freezing. There are various methods to protect against coil freezing. When the ambient air temperature falls below 0°C, the recirculating water within the fluid cooler can freeze.
Marley / MC Fluid Cooler / Engineering Data: Water Quality The MC Fluid Cooler can be a very effective air washer. Atmospheric dust able to pass through the relatively small louver openings will enter the recirculating water system. Increased concentrations can intensify systems maintenance by clogging screens and strainers—and smaller particulates can coat system heat transfer surfaces.
